摘要： An apparatus and method for making a three-dimensional object from a solidifiable material using a linear solidification device is shown and described. In certain examples, the linear solidification device includes a laser diode that projects light onto a scanning device, such as a rotating polygonal mirror or a linear scanning micromirror, which then deflects the light onto a photohardenable resin. As a result, the linear solidification device scans a line of solidification energy in a direction that is substantially orthogonal to the direction of travel of the laser diode. In other examples, the linear solidification device is a laser device array or light emitting diode array that extends in a direction substantially orthogonal to the direction of travel of the array.

摘要： Methods and apparatuses for making three-dimensional objects from multiple solidifiable materials is shown and described. Multiple solidifiable material container assemblies are provided for holding different solidifiable materials. Relative movement between the solidifiable material container assemblies and a build platform allows the solidifiable materials to be switched as an object is built. Several exemplary cleaning stations are provided for removing residual solidifiable materials from the surface of the three-dimensional object as it is built to better ensure smooth transitions between materials on the finished object.

摘要： The invention relates to a process or device for the production of a three-dimensional object by layer-wise solidification of a material which is solidifiable under the application of electromagnetic irradiation by means of mask illumination, wherein the mask is produced using an image forming unit having a prescribed resolution, which is formed from a constant number of image forming elements (pixels) being discrete and being arranged in a spatially mutually fixed manner. For the improvement of the resolution along the outer and inner contours of the sectional areas of the object to be generated layer-wise in the sub-pixel range, a multiple illumination per layer is performed, which consists of a series of multiple images that are mutually shifted in the sub-pixel range in the image/construction plane, wherein a separate mask/bitmap is produced for each shifted image.

摘要： The invention relates to a process or a device for the production of a three-dimensional object by layer-wise solidification of a photo-polymerizable resin by means of a planar or essentially planar construction/reference plane, at which the photo-polymerizable resin contained in the liquid material is to be hardened by electromagnetic irradiation, and wherein the material application for the subsequent layer automatically results from the separation of the last hardened layer from the construction/-reference plane, whereby the construction/reference plane is formed by an elastic film. The film is fixed in a frame, and the height position of the frame with the film is adjusted in a basin containing the liquid material such that the pressure of the liquid material compensates the sagging of the film (formation of a negative meniscus), and that the lower side of the film is permanently in contact with the material during the whole construction process.

摘要： A solidification substrate assembly for making a three-dimensional object from a solidifiable material includes a solidification substrate assembly. In certain examples, the solidifiable material solidifies in contact with the solidification substrate, and the tilting of the substrate and/or or the use of a peeling member facilitates separation of the substrate from the solidified material. In other examples, the solidification substrate assembly includes a film that is adjacent to a rigid or semi-rigid layer. The solidifiable material solidifies in contact with the film, and a peeling member peels the film away from the solidified material. Intelligent solidification substrate assemblies are also described in which a force sensor determines when to expose the solidifiable material to solidification energy and/or whether to use a peeling member to separate the solidification substrate from a solidified objection section.
